PADLOCK.

Appli-.sation filed May s1,

One object of my invention is to construct a substantial padlock in such a manner that the design of the casing can be altered materially, Without interfering With the assembling of the parts of the lock.

A still further object of the invention is to provide means for preventing a key, after it has been turned a given distance, from being removed from the lock until it has made a complete turn.

Another object of the invention is to improve the construction of the tumblers and the springs therefor.

These objects I attain in the following manner, reference being had to the accompanying drawings, in which:

Fig. 1 is a face view of the lock with one of the side plates removed and illustrating the mechanism;

Fig. 2 is a View, similar to Fig. 1., with some of the tumblers removed and showing the locking plate;

Fig. 3 is a View, similar to Fig. 2, with the lock plate removed;

Fig. 4 is a sectional View on the line 4-4, Fig. 1;

Fig. 5 is a ing bolt;

Fig. 6 is an edge view of the bolt;

Fig. 7 is a perspective view of the bolt with the parts detached; 'i

Fig. 8 is a detached side view of the change ward;

Fig. 9 is a. detached side view of the locking plate;

Fig. 10 is a detached side view of one of the tumblers;

Fig. 11 is an end View of one of the tumblers; and

Fig. 12 is a perspective View of one of the tumblers.

Referring to the drawings, 1 is the casing of the lock. 2 is the shackle pivoted at 3 to the casing and having a heel portion 4 on which is a pin 5. Bearing against this pin is a spring 6 mounted on a stud 7. The opposite end of the spring also rests against the casing, as shown in the drawings. The nose b of the shackle is slotted at 9, Fig. 3, for the reception of the head 10 of the bolt 11. The head is made separate from the bolt, as shown in Fig. 7, and is held thereto by two screws 12, in the presdetached side view of the slid-4 1923. serieu N5. 642,603.

ent instance. By this construction, heads of diierent shapes can be secured to a stand ard bolt. The bolt is slotted at 13 and at 14. rThe stud 7 extends through the slot 13 and a stud 15 extends through the slot 14. These two studs guide the bolt in its transverse movement The bolt has a pin 16, and a spring 17 is attached to this pin and to the stud 7, holding the bolt yieldingly in its locked position. The bolt is recessed at 13. 1n the wall of this recess is a shoulder 19 so that, when a. key is placed on the post 20 and is turned, it will lbear against the shoulder 19 and will retract the bolt against vthe pressure of the spring 17, releasing the shackle. Pivoted on the stud .15A is a change ward 21, slotted at 22 to receive the stump 23 on the bolt 11. The change ward is cut away at 25 and is shaped to receive the key and may be placed between any two tumblers to secure key changes.

26 designates a locking plate, which is pivotally mounted on the stud 15. This plate is recessed at 27 to receive the stump 23 on the bolt. The nose 28 rests on the stump as the key is partly turned, but, when the key passes the shoulder 29 in the plate, the plate drops over the stump of the bolt and prevents its being moved. The key is prevented from turning backward until a full revolution is made. A spring k24, mounted on a stud 30, bears against the locking plate, or detent, 26, as shown in Fig. 2.

Mounted on the stud 15 is a series of tumblers 31, shown clearly in Figs. 10, 11 and 12. These tumblers are cut away at 32 to receive the key. Some of the tumblers are cut away more than others to fit a particular key. The tumblers are notched at 33 to receive the stump 23 of the bolt. On the stud 30 are springs 34. One -arm of each spring rests in a slot 35 at the back 'of a tumbler and the other arm of the spring rests against the pin 16 on the bolt.

By the above construction, it will be seen that a substantial lock can be manufactured. The head of the bolt can be made in any shape desired and can be readily secured to the body of the bolt. By providing the lock with a locking plate, the bolt is locked firmly and the key cannot be turned back after it has been turned to a certain position so iii) that it is impossible to tamper with the lock by trying to throw the bolt without turning the key in the lock.

The locking plate has a rearward projection 36 with which the heel t engages, and, when in the closed position, the plate is lifted clear of the stump and of the lock.

I claim:

l. The combination in a padlock, of a casing; a shackle adapted to the casing, said shackle having` heel; a pin on the heel; a long spring pvotally mounted in the casing and bearing against the pin on the heel, a sliding bolt having a head arranged to engage the nose ot the shackle, said bolt h avving a. stump; a change nf'ard; a locking plate arranged to engage the stump; and tuinblcis arranged to align with the stump, said tinnblers locking the plate, and the `ward being controlled by a key.

2. The combination in a padlock, of a oasing; a shackle pivotod to the casing; a sliding bolt having` a head arranged to engage the nose ot the shackle, said bolt hai'fing a projecting stump; a change ward; a locking plate; a stnd on which the ward and the plate are pivotally mounted, said locking plate being recessed to engage the stump and having a shoulder to prevent the key from returning after it has moved the parte a given distance; and tumblers on said Stud, said tumblers being notched to receive the stump ot the bolt.

3. The combination in a padlock, of a casing; a shackle pivotally mounted in the casing, said shackle having a heel; a pin on the heel; a stnd at the opposite end ot the casing; a coiled spring on the stud having an arm bearing against the pin on the heel; a stud on the casing below the heel of the shackle; a bolt having` two slots through which the two studs extend, said bolt having a stump; a detachable head, said head being arranged to engage the nose of the shackle; a change wird; a locking plate; tnmblers pivotally n'ionnted on. the lower stud, said change ward having a slotto receive the stump of the holt, the locking plate being shaped to engage the stump; a shoulder on the locking plate, preventing the return of the key, the tumblers being slotted to receive the stump ot the bolt; a series of springs bearing upon the tnmblers; a pin on the bolt; and a coiled spring engaging the pin and tending to move the bolt in the locking position, said locking plate having a projection engaged by the heel of the shackle.
